The diamond particule coating on DRILAX hole saws give superior performance and lifetime. Please note our tools do not need center pilot holes. Center pilot hole drills are mostly for wood, metal, etc.

Drilax tools can drill 1 " in depth.

This set is for 5 pieces, all the same size : 3/4" This is the best value set if all you need is the 3/4 inch diamond drill bits.

Electroplated diamond coating will wear off if the tool gets too hot. Never let your drill bit run dry. Here is how you could use water to keep the tool cool:
a- You can build a mini water dam around the hole with plumbers putty.
b- You can choose to spray water on the drill bit.
c- Or you can use running water to cool the drill bit.

EASY TO USE

Please use protective gear.
